Changeset 96475 in vbox

Message:

IPRT: Resolve SetHandleInformation and GetHandleInformation dynamically and let the affected code deal with it specifically. Refactored the rtSocketCreate function to combine with setting inheritance, so we can use the WSA_FLAG_NO_HANDLE_INHERIT when available to avoid explicitly setting inheritance. Made RTSocketSetInheritance check the status before trying to set it, returning VERR_NET_NOT_UNSUPPORTED if tool old windows version. Also made GetVersionExW go via a function pointer since it wasn't there in NT 3.1. bugref:10261
